Explanation:
Reproduction is the process by which living organisms multiply themselves. They do this through two major ways namely: asexually and sexually. Sexual reproduction involves two organisms (male and female) that each donate a gamete (sperm and egg). In plants, the sexual reproductive structure is the FLOWER. The male flower is called STAMEN, while the female flower is called PISTIL.
However, plants can also be propagated asexually by making use of certain plant parts including tubers, leaf etc. TUBER is a structure in plant specifically used to asexually reproduce plants like yam, potato, cassava etc.
The correct answer would be the second option. The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical dysplasia. It is a pre-cancerous condition that involves an abnormal growth of cells in the lining of the endocervical canal which is the opening between the vagina and the uterus. A very common cause of developing this is the virus HPV or the human papillomavirus. It can be transmitted sexually and has many strains. This condition can still be cured when it is detected early. Without treating it, cervical dysplasia would develop to cancer.<span />
